For structural analysis and design the nominal values of dimensions shall be used. 135 I.1 Dutch national legislative deviations . 55 9.7.5 Torsional and flexural-torsional buckling .
90 BS EN 15512:2009 EN 15512:2009 (E) 5 A.1.2 Bend tests . These equivalent horizontal forces shall be applied at each level and shall be proportional to the factored vertical loads applied to the structure at that level, as shown in Figure 7. At the limit state, the sway component of the internal forces and deflections calculated using first order theory are enhanced due to second-order effects by the multiplication factor where V - V V = Sd cr cr (G.6) where V Sd is the design value of the vertical load on the frame. 120 B.3 Elastic critical value . This European Standard gives guidelines for the design of clad rack buildings where requirements are not covered in EN 1993. The UK participation in its preparation was entrusted to Technical Committee MHE/8, Steel shelving, bins and lockers. 8.1.4.2 Additional tests on steel The mechanical properties of basic materials shall be measured from tensile tests according to section A.1.1. 32 7.2 Combinations of actions for the ultimate limit state . 50 9.4.7 Design resistance with respect to web crippling .
